Miracles undermine secularism if it is correct that they imply that the
supernatural comes first.

They would suggest the existence of a superior power.

Miracles, such as the alleged visions of Mary at Lourdes and Fatima, have
encouraged large crowds to gather in disobedience to secular authority.

They would suggest that testimony to miracles justifies belief in miracles even
if the testimony is false.

Secularism is virtue. Anything against it is vice and wrong. The believers say
that God must take supreme importance in the world and in your life. Even when
they support secularism, they teach that it is only acceptable in the sense that
God gave the state a separate job to do from the Church. So even their
secularism is religious at least in intention. (It is saying, "We believers
support the separation of Church and state on religious grounds and because God
asks for it. If our religion tells us different or if God tells us different we
will oppose this separation. We only accept because we think God wants us to. If
we are wrong we will change our minds." Their secularism only looks like
secularism - it is not secularism. Their secularism contradicts and therefore
opposes true secularism. It holds that God's wishes come first.

It is ludicrous to think that a being such as God who is by definition the only
wholly good entity, would allow people to defy him by treating his principles
and his religion and himself as something that is unworthy of coming first. The
thought that God approves of secularism makes no sense.

True secularism does not care what God wants. Its neutral on religious
questions.
